Trial size 10 participants
Trial identifier NCT01546155, 2011P0022171


Healthy volunteers aged 21 to 50 are needed for a research study investigating whether pain will alter the binding properties of ([11C]diprenorphine), a molecule that can be used during brain imaging. Positron Emission Tomography (PET) and functional Magnetic Resonance (fMRI) imaging will be used in this study.

United States No locations recruiting

Masking open label
pet imaging
Up to a 120 minute PET scan using [11C]diprenorphine as the radiotracer
